Thank you very much for the critique, Mada! This gives me a great foundation to practice more, and I've taken notes of things to work on from your analysis, from both bolded and unbolded details.

I was often drawing lines with my hand hovering over the pages. Resting my palm lightly on the pages instead (while keeping my wrist steady, of course) has resulted in more confident strokes all around during warmups, and I hope to improve on that further throughout the 250 box challenge.
